Application November 22, 1955, Serial No. 548,342

2 Claims. (Cl. 43-43.13)

My nvention relates in general to trolling devices and in particular toa depth glider for use in deep sea fishing.

The principal object of my invention is to provide a glider which isadjustable to the depth at which it i's desired to fish and to the speedof travel during trolling.

Another object is to provide a device of this nature which shallmaintain a true course through the w'ater at the adjusted depth withouta swaying motion.

Another object has been to provided a depth glider which greatly reducesthe weight of sinkers necessary to fi'sh at any desired depth.

Moreover, my device is provided with an inclined vane extendinglongitudinally through said body for giving an initial down-Wardmovement of the body until the desired depth has been reached and formaintaining the body at such depth in stabilizing m'anner.

The above objects and advantages have been accomplished by the deviceshown in the accornpanying drawings, of which:

'Fig. 1 is a side elevation of my device showing the position it willassume when in use;

Fig. 2 is a sectional plan view taken on line II-II of Fig. 1; and

Fig. 3 is an end elevation of the device.

My invention comprises a body tubuliar in form and having a lengthsnbstantially greater than the diarneter thereof. An aperture 11 isformed in the side wall at the advance end 17 thereof for the receptionof the swivel 12 or the fishing line 13. In the diametrically oppositeside of the body and at the trailing end 1'8 thereof is provided anapertu-re 14 for the reception of the swivels 15 of the leader 16extending to the sinker or bait. A series of spaced apertures 19 areformed at the advance end of the body and are located diametrioallyopposite the aperture 1'1 for the attachment of a weight or sinker 20.The sinker is preferably carried by a removable Wire 21 which may beengaged with any one of the apentures 19 to alter the depth to which thebody will descend when trolling. All of the apertures just described arepreferably in a plane passing through the axis of the body.

Mounted within the body is a vane 22 which is secured to the oppositesides of the inner surface of the wall of tates Patent 2,765,573Patented Oct. 9, 1956 the body and which is inclined to the axis of thebody toward the advance end thereof so that when the device is beingdrawn through the water, the advance edge 23 of the vane will bedirected downw'ardly below the surface of the water to the desireddepth. The weight 20 is so proportioned that when the device istraveling through the water, the body and, therefore, the vane will haveits upper surface at inoreased inclination with the line of movement ofthe device when trol'lin-g. Since the weight 20 yis ladjus'table bymoving tfnom one of the apertures 19 to another, the angle of incidenceof the vane with the water may be altered slightly so as to govern thedepth at which the device will be maintained.

From the foregoing, it will be obvious that when the device is placed inthe water and is drawn forward'ly by the fishing line 13, it will becarried downvwardly into the water because of the inclin'ation of thebody and the vane and will assu-me a position substantially like thatshow-n in Fig. 1. Depending upon the weight and adjust- Inent of thesinker, the device will be carried down to the desired depth where itwill be maintained during the trolling per-iod. The function of the vane22 is, as hereinbefore pointed out, to aid in directing the devicedownvvardly into the water to the desired depth, but it also functionsto stabilize the movement of the body as it is being drawn through thewater thereby prevent-ing undesinable swaying.

What is claimed is:

1. A depth glider for use in trolling, comprising a tubular body, meanslocated at the top side of said body near the forward edge thereof forsecur-in-g a fishin-g line thereto, a sinker adapted to be secured tothe forward edge of said body at a point diametrical'ly opposite thepoint of attachment of the fishing line, a leader attached to thetrailing edge of said body on the same side as the attachment of saidsinker, and a vane eX'tend-ing across the interior of said body andinclined downfvvardly towa'rd the front thereof.

2. A depth glider for use in troll-img, comprisin'g a tubular body, saidbody having an advance end provided with an aperture for 'a fishing linelat the top side thereof and a bottom side provided with a plurality ofspaced sinker apertures, a fishing line secured to said fish-in-g lineaperture and a sinker adapted to be selectively secured to one of saidsinker apent'ures, said body having a trailing end provided with aleader aperture on the same side thereof as the sink'er apertures, and avane carried by said body and extending longitudin'ally therethrough andinclined downwardly toward said advance end of said body.
